Because the test execution model is intentionally different from JCK and 
other test harnesses like TestNG and JUnit.

jtreg specifies that a test is a series of actions, some of which may be 
compilation steps and some of which may be execution steps. It is not 
the case that all tests want to be compiled up front and then executed.

If you're testing consistent (or inconsistent) compilation, for example, 
you may want to compile some classes one way, then try compiling and 
using them a different way, as a way of testing separate compilation.   
There's a bunch of tests like that for serialization as well.

Bottom line: JDK tests are not always plain old API tests.
